Medical Dictionary Myelin Sheath (In Multiple Sclerosis): Myelin is a fatty material that creates a sheath that coats, insulates, and protects nerves of the brain and spinal cord. When the sheath is destroyed, communication between the nerve impulses and the body part are misdirected, slowed down, or incomplete. Symptoms of MS include: Vision problems. Emotional problems.

myelin sheath n. The insulating envelope of myelin that surrounds the core of a nerve fiber or axon and facilitates the transmission of nerve impulses. In the peripheral nervous system, the sheath is formed from the membrane of the Schwann cell, and in the central nervous system it is formed from oligodendrocytes. Also called medullary sheath.

Human Physiology/Print Version The myelin sheath is a fatty layer that protects nerve cells, extending to cover the nerve throughout its length, except in small, unmyelinated gaps known as the nodes of Ranvier. Myelin aids in accelerating the speed at which an impulse travels along a nerve by causing the impulse to jump from one node of Ranvier to the next. Damage to the myelin sheath, called demyelination, compromises the nerve’s ability to conduct impulses. Video of the Day

What is the myelin sheath and what does it do? Myelin is a fatty white substance that surrounds the axon dielectric (electrically insulating) material that forms a layer, the myelin sheath, usually around only the axon of a neuron. It is essential for the proper functioning of the nervous system.
